Abstract: The disclosure relates to a load cell for a linear actuator. The load cell configured to measure a force exerted thereon by a rotary motor, and includes a spring element, a hollow portion and at least one strain gauge. The spring element includes a first side and a second side. The first side and the second side are opposite to each other. The hollow portion passes through the spring element. The at least one strain gauge is secured on the spring element and located between the first side and the second side, wherein when the force is exerted on the spring element when the rotary motor is driven to move along the first direction, the second side is moved relative to the first side, the spring element is deformed, and the at least one strain gauge changes shape, so that the force is measured and standardized under a specific range.

Abstract: A measuring arrangement for a shaping machine includes a measuring diaphragm deformable by a force action, a measuring device for metrological detection of a deformation of the measuring diaphragm with the output of a measurement signal, and an evaluation device connected to the measuring device. The evaluation device, in the course of a first calibration, can convert the measurement signal originating from the deformation of the measuring diaphragm with a force from a first force value range into a first output signal, and the first output signal is in a previously defined value range. The evaluation device, in the course of a second calibration, can convert the measurement signal originating from the deformation of the measuring diaphragm with a force from a second force value range differing from the first force value range into a second output signal, and the second output signal is in the previously defined value range.
